Nutec Bickley provides industrial Steel Tempering furnace in custom designs and dimensions to match customer production and process requirements.

Vitrified Clay Pipe (VCP) is a very natural product that has been around for 2,000 years. The main benefit over concrete or plastic pipe is their long life and resistance to corrosive conditions. Many architects and planners specify them as the best option. There are different types of VCP to depending upon the connection methods which usually combine the formed shape as well as plastic or rubber seals.

Fired tolerances should be tight for a good pipe to pipe fit and this is achieved with very consistent firing conditions.

The kilns are usually large to accommodate big volumes of large product and firing cycles are slow and uniform to give the highest quality pipes.

Nutec Bickley supplies Tunnel Kilns and Shuttle Kilns with the latest technology in combustion and controls to fire Vitrified Clay Pipe and fittings from small to large diameters.

  • Biscuit firing: a firing process for carefully removing carbon material from a product; as the temperature rises the process forms strong ceramic bonds which are critical to the strength and performance of the pipes. Uniform firing leads to more consistently shaped fired products which is important to meet tight size tolerances.
  • Glaze firing: some clay bodies do not fully vitrify during biscuit firing, so the pipes are glazed and refired to improve performance and also to reduce water absorption.
